Abstract
BACKGROUND The risk of suffering epithelial ovarian cancer (EOC) for women increases with age evidently, while the prognosis of older EOC patients remain unclear. Against the backdrop of the accelerate aging process in China, this paper investigates whether the older EOC patients have a lower overall survival probability than the younger patients based on the sample of ethnic Chinese population. METHODS A total of 323 ethnic Chinese patients diagnosed as epithelial ovarian cancer were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. We compared the overall survival probability between the younger group (< 70 years) and the older patients group (≥ 70 years). Survival curves were drawn using the Kaplan-Meier method, comparisons among different subgroups were evaluated using log-rank tests, and independent prognostic factors were identified by univariate and multivariate Cox regression analyses. RESULTS 43 patients were (13.3%) in the older patients group and 280 (86.7%) in the younger group. The distribution patterns between two groups were significantly different with regard to marital status, histologic type and FIGO stage. The median overall survival (OS) was significantly longer in the younger group than the older patients group (not reached vs. median 39 months, p < 0.05). The multivariate analysis demonstrated that the age (The older vs. the younger, HR: 1.967, P = 0.007), primary tumor laterality (HR: 1.849, P = 0.009), and FIGO stage (III vs. I, HR: 3.588, P = 0.001; and IV vs. I, HR: 4.382, P = 0.001; respectively) remained as important risk factors while Histology (HGSOC vs. CCOC, HR: 0.479, P = 0.025; and LGSOC/MOC/EC vs. CCOC, HR: 0.390, P = 0.034; respectively) and the number of lymph node dissected more than 10 was a protective factor (HR: 0.397, P = 0.008). In an analysis of 104 pairs of patients matched on the basis of the propensity score, the older patients group had significantly lower overall mortality (HR = 2.561, P = 0.002). CONCLUSION Ethnic Chinese Older EOC patients have a worse prognosis than the younger patients.

Abstract
Importance Single-agent carboplatin is often proposed instead of a conventional carboplatin-paclitaxel doublet in vulnerable older patients with ovarian cancer. Such an approach could have a detrimental effect on outcomes for these patients. Objective To compare the feasibility, efficacy, and safety of single-agent carboplatin every 3 weeks, weekly carboplatin-paclitaxel, or conventional every-3-weeks carboplatin-paclitaxel in vulnerable older patients with ovarian cancer. Design, Setting, and Participants This international, open-label, 3-arm randomized clinical trial screened 447 women 70 years and older with newly diagnosed stage III/IV ovarian cancer by determining their Geriatric Vulnerability Score; 120 patients with a Geriatric Vulnerability Score of 3 or higher were stratified by country and surgical outcome. Enrollment took place at 48 academic centers in France, Italy, Finland, Denmark, Sweden, and Canada from December 11, 2013, to April 26, 2017. Final analysis database lock April 2019. Data analysis was performed from February 1 to December 31, 2019. Interventions Patients were randomized to receive 6 cycles of (1) carboplatin, area under the curve (AUC) 5 mg/mL·min, plus paclitaxel, 175 mg/m2, every 3 weeks; (2) single-agent carboplatin, AUC 5 mg/mL·min or AUC 6 mg/mL·min, every 3 weeks; or (3) weekly carboplatin, AUC 2 mg/mL·min, plus paclitaxel, 60 mg/m2, on days 1, 8, and 15 every 4 weeks. Main Outcomes and Measures The primary outcome was treatment feasibility, defined as the ability to complete 6 chemotherapy cycles without disease progression, premature toxic effects-related treatment discontinuation, or death. Results A total of 120 women were randomized. The mean and median age was 80 (interquartile range, 76-83; range, 70-94) years; 43 (36%) had a Geriatric Vulnerability Score of 4 and 13 (11%) had a Geriatric Vulnerability Score of 5; 40 (33%) had stage IV disease. During its third meeting, the independent data monitoring committee's recommendation led to the termination of the trial because single-agent carboplatin was associated with significantly worse survival. Six cycles were completed in 26 of 40 (65%), 19 of 40 (48%), and 24 of 40 (60%) patients in the every-3-weeks combination, single-agent carboplatin, and weekly combination groups, respectively. Treatment-related adverse events were less common with the standard every-3-weeks combination (17 of 40 [43%]) than single-agent carboplatin or weekly combination therapy (both 23 of 40 [58%]). Treatment-related deaths occurred in 4 patients (2 of 40 [5%] in each combination group). Conclusions and Relevance This randomized clinical trial shows that compared with every-3-weeks or weekly carboplatin-paclitaxel regimens, single-agent carboplatin was less active with significantly worse survival outcomes in vulnerable older patients with ovarian cancer. Trial Registration ClinicalTrials.gov Identifier: NCT02001272.

Abstract
AIM Since there are no established guidelines for the treatment of gynecological cancer in the elderly, medical treatment policy is currently decided by discussion with patients and their families based on doctors' experiences, referring to data from nonelderly patients and healthy elderly patients. The aim of this review was to clarify the current position of chemotherapy for elderly gynecological cancer patients and discuss the problems to be addressed in the future. METHODS Little evidence has been accumulated for anticancer drug treatment in elderly individuals with gynecological cancer. This review presents outlines and representative papers on general cancer chemotherapy for the elderly, and problems that need to be solved in gynecological cancer fields in the future are identified. RESULTS In 2018, the American Society of Clinical Oncology (ASCO) published guidelines for "Practical Assessment and Management of Vulnerabilities in Older Patients Receiving Chemotherapy: ASCO Guideline for Geriatric Oncology Summary". This guideline emphasizes that, when administering chemotherapy to patients over 65 years of age, vulnerabilities should be identified using geriatric assessment (GA). However, there have been no reports of clinical studies using GA in patients with cervical or uterine cancers, and only a few clinical studies using GA have been reported in patients with ovarian cancer. CONCLUSIONS Scoring systems suitable for elderly Japanese patients remain lacking. A Japanese gynecological GA needs to be developed in cooperation with other disciplines.

Abstract
Objective Ovarian cancer is the most lethal cancer involving the female pelvic reproductive system. Its incidence increases with age and with an aging population, its prevalence should also increase. The goal of our retrospective study is to report our experience in treating women over 65 years of age, with a diagnosis of primary ovarian cancer, using standard intravenous chemotherapy. Methods The medical records of 78 patients>65 years of age diagnosed with primary ovarian cancer at the Yale Cancer Center between 1996–2006 were retrospectively reviewed and included in our analysis. Patients had stage I–IV disease (stage I n=5, stage II n=8, stage III n=36, stage IV n=25, unknown n=4). Results Sixty-three of 78 women (80.8%) completed the prescribed regimen; and 62 women did not require a dose reduction or chemotherapy discontinuation. The most common reason for a dose reduction or treatment discontinuation was fatigue (6.4%), neutropenia (2.6%), patient preference (2.6%), and multiple co-morbidities (2.6%). The most commonly used regimen was paclitaxel 175mg/m2 and carboplatin AUC 5. The hazard ratio for PFS and OS for patients who had dose reduction/discontinuation versus those who completed the prescribed dose was 1.3 (95% CI 0.51–3.26) and 0.63 (95% CI 0.17–2.33), respectively. Conclusions Our findings illustrate that elderly women are able to tolerate standard chemotherapy with relatively few significant adverse effects. While different treatment modalities in ovarian cancer are continually being evaluated, additional prospective studies are required to better understand the tolerability and efficacy of such treatment in the elderly population.

Abstract
Ovarian cancer is the seventh most common cancer in women worldwide and accounts for nearly 4% of all new cases of cancer in women. Almost half of all patients with ovarian cancer are over the age of 65 at diagnosis, and over 70% of deaths from ovarian cancer occur in this same age group. As the population ages, the number of older women with ovarian cancer is increasing. Compared to younger women, older women with ovarian cancer receive less surgery and chemotherapy, develop worse toxicity, and have poorer outcomes. They are also significantly under-represented in clinical trials and thus application of standard treatment regimens can be challenging. Performance status alone has been shown to be an inadequate tool to predict toxicity of older patients from chemotherapy. Use of formal geriatric assessment tools is a promising direction for stratifying older patients on trials. Elderly-specific trials, adjustments to the eligibility criteria, modified treatment regimens, and interventions to decrease morbidities in the vulnerable older population should be encouraged.

Abstract
INTRODUCTION In patients with non-metastatic muscle-invasive bladder cancer (MIBC) fit for curative therapy, a multidisciplinary approach consisting is recommended. This approach includes local treatment (usually radical cystectomy), ideally combined with neoadjuvant chemotherapy (NACT). Despite a survival benefit with NACT, uptake remains low. We assessed NACT consultation in Alberta and examined associative factors, as well as the relationship to survival. METHODS Patients with MIBC were identified through the Alberta Cancer Registry. Demographic and clinicopathologic information was collected from electronic medical records between 2007 and 2011. In addition to descriptive statistics, logistic regression was used to determine factors associated with receiving NACT consultation. Overall survival was described using a Kaplan-Meier estimate. RESULTS Of the 315 radical cystectomy patients, 140 (45.1%, 95% confidence interval [CI] 39.5, 50.8) received NACT consultation. Patients ≥80 years (odds ratio [OR] 0.21, 95% CI 0.08, 0.57, p = 0.002) and those treated in Calgary (OR 0.11, 95% CI 0.05, 0.25, p < 0.001) were less likely to receive NACT consultation. The rate of NACT consultation increased steadily from 2007 to 2011 (OR 1.23, 95% CI 1.04, 1.45 per year of diagnosis, p = 0.018). After a median follow-up of 28.1 months (range: 14.6-50.3), median survival was 54.7 months for patients who received NACT consultation versus 31.2 months for those who did not (p = 0.030). CONCLUSIONS NACT consultation in patients with MIBC undergoing radical cystectomy has improved over time; however, regional differences underscore the need for a standardized approach to NACT consultation, including common referral mechanisms.

Abstract
Nearly half of all women diagnosed with breast or ovarian cancer are age 65 years or older with the number of women diagnosed expected to increase as the population ages and life expectancy improves. Older women are less likely to be offered standard cancer treatments, are more likely to develop higher toxicity, and have higher mortality. Chronologic age should not be the only factor used for making treatment decisions. Functional dependence, organ function, comorbidity, polypharmacy, social support, cognitive and/or psychosocial factors, overall life expectancy, and patient's goals of care are equally vital and should be assessed before and during treatment. In this review, current evidence and treatment guidelines for older women with breast or ovarian cancer are outlined.

Abstract
Approximately 70% of women with epithelial ovarian cancer (EOC) are diagnosed with advanced stage disease, which is associated with high morbidity and mortality. The standard approach to treating patients with advanced EOC remains primary debulking surgery (PDS) followed by chemotherapy. EOC is one of the most sensitive of all solid tumors to cytotoxic drugs, with over 80% of women showing a response to standard chemotherapy combined with taxane and platinum. Furthermore, residual disease is a major prognostic factor for survival. On the basis of the clinical features, neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS) is considered to be an alternative treatment option to standard treatment in patients unable to undergo complete resection during PDS. Noninferiority of NACT-IDS to PDS has been demonstrated in some randomized controlled trials and meta-analyses. NACT would also lead to improved quality of life (QOL) of patients, however there are still problems to be solved in the treatment strategy. The uncertainty of perioperative visual assessment of tumor dissemination after NACT has been reported. In addition, several papers have shown the possibility that NACT induces platinum resistance. Furthermore, a notable risk associated with NACT is that patients with significant side effects and refractory disease will lose the opportunity for debulking surgery. Appropriate selection of the patient cohort for NACT is an important issue. Bevacizumab (Bev) is active in patients with advanced EOC. However, the use of Bev is not recommended in the neoadjuvant setting. Bev has a specific adverse event profile that needs to be considered, especially for surgical management, such as gastrointestinal perforation, hemorrhage, and thromboembolic events. NACT could be an alternative treatment option in patients with stage III or IV EOC. However, further studies are needed to clarify the precise role of NACT in the management of advanced EOC.

Abstract
BACKGROUND In prior research, we developed a claims-based prediction model for poor patient disability status (DS), a proxy measure for performance status, commonly used by oncologists to summarize patient functional status and assess ability of a patient to tolerate aggressive treatment. In this study, we implemented and validated the DS measure in 4 cohorts of cancer patients: early and advanced non-small cell lung cancers (NSCLC), stage IV estrogen receptor-negative (ER-) breast cancer, and myelodysplastic syndromes (MDS). DATA AND METHODS SEER-Medicare data (1999-2007) for the 4 cohorts of cancer patients. Bivariate and multivariate logistic regression tested the association of the DS measure with designated cancer-directed treatments: early NSCLC (surgery), advanced NSCLC (chemotherapy), stage IV ER- breast cancer (chemotherapy), and MDS (erythropoiesis-stimulating agents). Treatment model fit was compared across model iterations. RESULTS In both unadjusted and adjusted results, predicted poor DS was strongly associated with a lower likelihood of cancer treatment receipt in all 4 cohorts [early NSCLC (N=20,280), advanced NSCLC (N=31,341), stage IV ER- breast cancer (N=1519), and MDS (N=6058)] independent of other patient, contextual, and disease characteristics, as well as the Charlson Comorbidity Index. Inclusion of the DS measure into models already controlling for other variables did not significantly improve model fit across the cohorts. CONCLUSIONS The DS measure is a significant independent predictor of cancer-directed treatment. Small changes in model fit associated with both DS and the Charlson Comorbidity Index suggest that unobserved factors continue to play a role in determining cancer treatments.

Abstract
To improve the benefit and tolerability of cancer treatment, we must develop new geriatric-specific trials, better assessment tools, and encourage enrollment of older patients in clinical trials. Age is a strong predictor of survival in ovarian cancer and often influences the treatment plan. Elderly patients, broadly defined as older than age 65 years, are commonly not offered participation in clinical research or provided with substandard chemotherapy or surgical options. Because first-line, platinum-based chemotherapy with cytoreductive surgery is a potentially curative modality, all standard treatment options should be explored (intravenous, neoadjuvant, and/or intraperitoneal chemotherapy). However, one must balance the specific needs of the older patient and be aware of the increased risk of side effects. To be mindful and respectful, the oncologist should clearly define the goals (palliative vs. curative) and specific risks of treatment to patients and their families. As the field of geriatric oncology evolves and prospective trials tailored to older women with ovarian cancer are developed, specific guidelines will ultimately assist in these difficult decisions.

Abstract
OBJECTIVE To compare primary debulking surgery (PDS) vs. neoadjuvant chemotherapy with interval debulking surgery (NACT-IDS) among elderly patients with ovarian/fallopian tube/primary peritoneal carcinoma. METHODS Medical records of patients ≥70 years old with epithelial ovarian/fallopian tube/primary peritoneal carcinoma between January 2000 and December 2010 were reviewed. Patients were separated by PDS or NACT-IDS. Preoperative characteristics, surgical procedures and postoperative and oncologic outcomes were compared. Surgical procedures were given a complexity score based on a previously published method. RESULTS Of 165 patients, 125 (75.8%) underwent PDS and 40 (24.2%) underwent NACT-IDS. Patients undergoing NACT-IDS were more likely to have a pleural effusion (without cytology) and stage 4 disease. Median CA-125 at diagnosis was greater for those undergoing NACT-IDS. The NACT-IDS group was associated with less intraoperative blood loss (250 vs. 400 mL, p=0.001), a greater chance of achieving no residual disease (40% vs. 16%, p=0.005) and a shorter hospital length of stay (LOS) (5 vs. 7 days, p<0.001). PFS (17 vs. 15 months, p=0.708) and OS (29 vs. 33 months, p=0.827) were similar between the two groups. Readmission rates within 30 days of surgery were greater in those undergoing PDS (17.6% vs. 2.5%, p=0.016). After readmission, the median hospital LOS was 6 days (range: 1-41). CONCLUSIONS Elderly patients undergoing PDS have similar oncologic outcomes when compared to patients undergoing NACT-IDS. The risk of readmission within 30 days of surgery is significantly greater among patients undergoing PDS.

Comparative effectiveness of platinum-based chemotherapy versus taxane and other regimens for ovarian cancer. Med Oncol 2013; 30:440. [PMID: 23307252 DOI: 10.1007/s12032-012-0440-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2012] [Accepted: 11/30/2012] [Indexed: 10/27/2022]
Abstract
The aim was to compare the two most commonly recommended chemotherapy regimens (platinum-based chemotherapy and platinum-taxane combination) with non-platinum-based chemotherapy and those with no chemotherapy in a large nationwide and population-based cohort of patients with ovarian cancer with up to 17 years of follow-up. We studied 12,181 patients diagnosed with stages I-IV ovarian cancer at age ≥ 65 in 1991-2005 from the 16 areas of the United States. We also performed matched cohort analyses based on conditional probability of receiving platinum chemotherapy in 3,428 patients. In patients with early stage ovarian cancer, those who received platinum-taxane combination had the highest 5-year all-cause (62.5 %) and cancer-specific (65.1 %) survival rates, as compared to 51.5 and 63.7 % in those without chemotherapy. After adjusting for potential confounders, hazard ratios of all-cause mortality (0.66, 95 % CI 0.55-0.79) and cancer-specific mortality (0.74, 0.61-0.90) were significantly lower in patients receiving platinum-taxane combination as compared to those without chemotherapy. Among patients with late-stage ovarian cancer, risks of mortality were significantly reduced in patients who received both platinum and taxane (0.38, 0.36-0.41 for all-cause mortality; 0.40, 0.37-0.42 for cancer-specific mortality). Dose-response relationship appeared strong within each of the three chemotherapy regimens. These results and trends were almost identical in the matched cohort. Platinum-taxane combination chemotherapy and platinum-based chemotherapy without taxane were effective in prolonging survival with a significant dose-response relationship among patients with late-stage ovarian cancer. Among those with early stage tumors, platinum-taxane combination appeared more effective than other chemotherapy regimens.

Abstract
Ovarian cancer (OC) is a disease of elderly women. The disease spreads insidiously and presents at an advanced stage at initial diagnosis for most patients. Several groups reported at least a two-fold increased risk of death in women older than 65. Various theories have been proposed to explain this survival disparity in older women, including: (1) more aggressive cancer with advanced age, (2) inherent resistance to chemotherapy, (3) individual patient factors such as multiple concurrent medical problems, and (4) physician and health-care biases toward the elderly that lead to inadequate surgery, less than optimal chemotherapy, and poor enrollment in clinical trials. As a result of this high clinical variability, oncologists need to be more familiar with the comprehensive geriatric assessment to better identify vulnerable patients at higher risk of complications. Several geriatric tools are available to assess the physiologic and functional capacities of older patients and to better individualize treatment. This paper gives an overview of the management of elderly patients with OC, in particular the integration of chemotherapy, surgery, and geriatric assessment to improve treatment tolerance and survival outcomes.

Abstract
The goal of comparative effectiveness research is to inform clinical decisions between alternate treatment strategies using data that reflect real patient populations and real-world clinical scenarios for the purpose of improving patient outcomes. Observational studies using population-based registry data are increasingly relied on to fill the information gaps created by lack of evidence from randomized controlled trials. Administrative data sets have many advantages, including large sample sizes, long-term follow-up, and inclusion of data on physician and systems characteristics as well as cost. In this review, we describe the characteristics of many of the commonly used population-based data sets and discuss the elements included within these data sets. An overview of common research themes that rely on population-based data and illustrative examples are presented. Finally, an overview of the analytic techniques commonly employed by health services researchers to limit the effects of selection bias and confounding is discussed. The analysis of well-designed studies of comparative effectiveness is complex. However, careful framing, appropriate study design, and application of sophisticated analytic techniques can improve the accuracy of nonrandomized studies. There are multiple areas where the unique characteristics of observational studies can inform medical decision making and health policy, and it is critical to appreciate the opportunities, strengths, and limitations of observational research.

Abstract
The aging of the population has focused on the need to evaluate older patients with cancer. Approximately 50% of patients with ovarian cancer will be older than age 65 years. Increasing age has been associated with decreased survival. It is uncertain whether this relates to biologic factors, treatment factors, or both. There is concern that undertreatment may be associated with decreased survival. Older patients with ovarian cancer have been underrepresented in clinical trials. Therefore, the evidence base on which make decisions is lacking. Clinicians need to be aware of the currently available data to aid in treatment decisions. Doublet therapy is the most common standard treatment in epithelial ovarian cancer. It usually consists of a taxane and a platinum compound. A series of cooperative group studies in both the United States and Europe established intravenous paclitaxel and carboplatin as the most common standard in optimally debulked patients. The recent introduction of intraperitoneal therapy has complicated decision making in terms of which older patients would benefit from this more toxic therapy. In relapsed patients, the issue of platinum sensitivity is critical in deciding whether to reutilize platinum compounds. It is unclear whether single agents or combinations are superior, particularly in older patients. Geriatric assessment is an important component of decision making. Prospective studies are needed to develop strategies to determine the optimal treatment for older patients with ovarian cancer.

Abstract
Purpose This analysis identifies factors associated with completion of adjuvant chemotherapy for patients with ovarian cancer and subsequent use of health services. Patients and Methods We used the Surveillance, Epidemiology, and End Results (SEER) –Medicare database to identify 4,617 women age 65 years or older with ovarian cancer diagnosed from 2001 to 2005. By using multivariable analyses with completion of chemotherapy as the outcome of interest, we describe factors associated with completion of treatment, including age, race, marital status, comorbidities, and sociodemographic factors. Use of health services was captured from Medicare claims. Results Among 4,617 patients with untreated ovarian cancer, 1,329 (28.8%) received no chemotherapy, 1,139 (24.7%) received a partial course of chemotherapy, and 2,149 (46.5%) completed chemotherapy. Women age 75 years or older were at greater risk of incomplete chemotherapy versus women age 65 to 74 years (odds ratio [OR], 1.64; 95% CI, 1.33 to 2.04). Having two or more comorbidities was also significantly associated with incomplete chemotherapy (OR, 1.83; 95% CI, 1.34 to 2.50). Among women who received either a partial or complete course of chemotherapy, we did not find an increase in use of health services (hospitalizations, emergency department visits, or physician visits) for the oldest women (age 80 years or older) compared with younger women. Conclusion There is considerable room for improvement in helping older patients with ovarian cancer initiate and complete chemotherapy. The oldest women who completed chemotherapy in this study did not use health services more than younger women did. Treatment teams for older patients with ovarian cancer should include expertise in geriatric assessment, should carefully identify medical and psychosocial barriers to completing treatment, and should support patients throughout treatment.

Abstract
BACKGROUND An increasing need has developed for the post-approval surveillance of (new) anti-cancer drugs by means of pharmacoepidemiology and outcomes research in the area of oncology. OBJECTIVES To create an overview that makes researchers aware of the available database linkages in Northern America and Europe which facilitate pharmacoepidemiology and outcomes research in cancer patients. METHODS In addition to our own database, i.e. the Eindhoven Cancer Registry (ECR) linked to the PHARMO Record Linkage System, we considered database linkages between a population-based cancer registry and an administrative healthcare database that at least contains information on drug use and offers a longitudinal perspective on healthcare utilization. Eligible database linkages were limited to those that had been used in multiple published articles in English language included in Pubmed. The HMO Cancer Research Network (CRN) in the US was excluded from this review, as an overview of the linked databases participating in the CRN is already provided elsewhere. Researchers who had worked with the data resources included in our review were contacted for additional information and verification of the data presented in the overview. RESULTS The following database linkages were included: the Surveillance, Epidemiology, and End-Results-Medicare; cancer registry data linked to Medicaid; Canadian cancer registries linked to population-based drug databases; the Scottish cancer registry linked to the Tayside drug dispensing data; linked databases in the Nordic Countries of Europe: Norway, Sweden, Finland and Denmark; and the ECR-PHARMO linkage in the Netherlands. Descriptives of the included database linkages comprise population size, generalizability of the population, year of first data availability, contents of the cancer registry, contents of the administrative healthcare database, the possibility to select a cancer-free control cohort, and linkage to other healthcare databases. CONCLUSIONS The linked databases offer a longitudinal perspective, allowing for observations of health care utilization before, during, and after cancer diagnosis. They create new powerful data resources for the monitoring of post-approval drug utilization, as well as a framework to explore the (cost-)effectiveness of new, often expensive, anti-cancer drugs as used in everyday practice.

Abstract
BACKGROUND A study was undertaken to determine the survival benefit of postoperative chemoradiation therapy for elderly patients with resected gastric adenocarcinoma. METHODS The authors identified 1023 individuals aged 65 years and older (median = 76) who underwent gastrectomy for nonmetastatic stage IB-IV gastric adenocarcinoma diagnosed between 2000 and 2002 in the linked Surveillance, Epidemiology, and End Results-Medicare database. They examined factors associated with receiving postoperative chemoradiation and analyzed the survival benefit associated with receiving postoperative chemoradiation. RESULTS Thirty percent of patients received adjuvant chemoradiation. On multivariate analysis, younger age (P < .0001), lymph node involvement (P < .0001), and more recent diagnosis (P = .0284) were associated with receiving chemoradiation. There was a trend toward increased use among patients with less comorbidity (P = .0515). The median follow-up was 25.5 months, and 62% died. On multivariate survival analysis, older patients (P < .0001) and those with lymph node involvement (P < .0001), T3 or T4 disease (P = .0472), higher grade disease (P = .0355), and more comorbidity (P = .0411) were more likely to die. After adjustment for other factors, receipt of adjuvant chemoradiation therapy did not significantly increase survival (hazard ratio, 0.90; 95% confidence interval, 0.72-1.12; P = .3453) and did not increase survival in a multivariate analysis that included propensity scores (P = .2090). CONCLUSIONS The authors did not detect a survival benefit, suggesting that some elderly patients with resected gastric adenocarcinoma may not gain a survival benefit from the administration of adjuvant chemoradiation. The analysis had limitations, and the results are hypothesis generating. Future gastric cancer trials should enroll more elderly patients and stratify patients by age to better understand the impact of treatment regimens on older patients.

Abstract
OBJECTIVES Ovarian cancer (OC) typically is diagnosed at advanced stages, in which the primary goal of therapy is to prolong progression-free survival (PFS) and overall survival (OS). In recent years, maintenance therapy has been tested for this purpose in advanced OC (AOC). Literature on maintenance therapy in AOC was systematically reviewed to assess current knowledge regarding the impact of this therapeutic approach. METHODS A MEDLINE search was performed 2/2009 for articles published 1/2001-1/2009 pertaining to OC maintenance therapy guidelines, patterns, and outcomes. A second search used keywords specific to maintenance and included primary studies published in the last 10 years. Of 406 sources identified, 36 primary studies and 16 review articles were included in this systematic review. A third search used the keyword "consolidation" to find maintenance articles not identified through other searches; of 48 additional sources, 13 primary studies and 6 reviews were included. A fourth search of non-MEDLINE-indexed sources yielded 14 additional relevant publications from the same time period. RESULTS Among practice guidelines identified, only the National Comprehensive Cancer Network (NCCN) 2008 guidelines provide recommendations regarding maintenance therapy, assigning it a category 2B recommendation. No studies were identified that reported current treatment patterns or economic outcomes in maintenance therapy; quality of life data were reported in one study. A variety of agents have been tested for maintenance, with paclitaxel the most commonly evaluated. The Southwest Oncology Group-Gynecologic Oncology Group 178 trial has found that 12 cycles of paclitaxel extend PFS (by 7 months) compared to 3 months paclitaxel, but could not adequately evaluate OS. CONCLUSIONS Maintenance therapy may improve clinical outcomes in AOC, but additional research is needed to demonstrate an OS advantage. Future studies should investigate the long-term clinical benefit of maintenance treatment and its impact on resource utilization and health-related quality of life.

Abstract
PURPOSE Anthracycline-based chemotherapy, which improves survival for patients with non-Hodgkin's lymphoma, is often withheld from elderly patients because of its cardiotoxicity. We studied the cardiac effects of doxorubicin in a population-based sample of older patients with diffuse large B-cell lymphoma (DLBCL). PATIENTS AND METHODS Among patients age > or = 65 years diagnosed with DLBCL from 1991 to 2002 in the Surveillance, Epidemiology, and End Results-Medicare database, we developed logistic regression models of the associations of doxorubicin with demographic, clinical, and cardiac variables. We then developed Cox proportional hazards models of the association between doxorubicin and subsequent congestive heart failure (CHF), taking predictors of CHF into account. RESULTS Of 9,438 patients with DLBCL, 3,164 (42%) received doxorubicin-based chemotherapy. Any doxorubicin use was associated with a 29% increase in risk of CHF (95% CI, 1.02 to 1.62); CHF risk increased with number of doxorubicin claims, increasing age, prior heart disease, comorbidities, diabetes, and hypertension; hypertension intensified the effect of doxorubicin on risk of CHF (hazard ratio = 1.8; P < .01). In the 8 years after diagnosis, the adjusted CHF-free survival rate was 74% in doxorubicin-treated patients versus 79% in patients not treated with doxorubicin. CONCLUSION Among patients receiving chemotherapy for DLBCL, those with prior heart disease were less likely than others to be treated with doxorubicin, and those who received doxorubicin were more likely than others to develop CHF. Various cardiac risk factors increased CHF risk, but only hypertension was synergistic with doxorubicin. Doxorubicin has dramatically improved survival of DLBCL patients; nonetheless, some subgroups may benefit from efforts to reduce doxorubicin-related CHF risk.

Abstract
Due to the higher risk of morbidity and perioperative mortality compared to younger patients, elderly patients with advanced ovarian cancer are challenging to treat. A population-based analysis was performed to predict treatment outcomes and establish risk factors for early death of elderly patients with advanced ovarian cancer using a cohort of 3994 women diagnosed with stage III or IV ovarian cancer between 1992 and 1999, registered with the Surveillance, Epidemiology and End Results Cancer Registries. A multivariate accelerated failure time model allowed estimation of a risk factor model for overall survival. Patient's age, stage at presentation, presence of comorbidities, and oncology treatment facility were independently associated with overall survival at 12 months from diagnosis. Patients were assigned to low (0–7 points), moderate (8–14 points) or high (≥15 points) risk groups according to accumulation of risk factors, which showed good ability to predict 12-month mortality (receiver–operator characteristics curve [ROC] derivation cohort = 0.763; ROC validation cohort = 0.756). Across all three risk groups, patients who received both surgery and chemotherapy showed significantly improved survival as compared to patients who received only surgery or chemotherapy. For patients 80 years and over who had upfront surgery, perioperative mortality was significantly greater in the high-risk group (21%; 95% CI = 16–26%) compared to patients within the moderate (8%; 95% CI = 5–12%) and low-risk groups (0%; 95% CI = 0–11%). The risk factor profile established could be helpful to plan future clinical trials to establish optimal treatment for elderly patients with advanced stage ovarian cancer

Abstract
The purpose of the study was to determine the ethnic disparities in socioeconomic status (SES) and in receiving definitive surgical treatment and adjuvant chemotherapy and to examine if these differences contribute to ethnic disparities in survival. We studied a population-based cohort of 5131 women diagnosed with epithelial ovarian cancer at age >or=65 between 1992 and 1999, identified from the Surveillance, Epidemiology and End Results-Medicare linked databases with up to 11 years of follow-up. The percentage of women diagnosed with epithelial ovarian cancer at advanced stage (stage III or IV) was 71.6% in Caucasians and 69.7% in African-Americans. Of these 4264 with stage IC-IV disease who are recommended for chemotherapy, fewer African-Americans received chemotherapy compared to Caucasians (50.2% versus 64.7%, P < 0.001). The risk of all-cause mortality in African-Americans was not significantly different from Caucasians (hazard ratio [HR] = 1.00, 95% CI = 0.88-1.13) after controlling for patient demographics, tumor characteristics, and comorbidity. The HR remained not significant in African-Americans compared to Caucasians after additionally adjusting for treatments (0.93, 0.82-1.06) or SES (0.94, 0.82-1.08) or both (0.88, 0.77-1.01). Women who underwent cancer-directed surgery and received adjuvant chemotherapy were 50% less likely to die than those who did not. The survival benefits from these therapies were similar in Caucasian and African-American women with ovarian cancer. There was no significant difference in survival between African-American and Caucasian women with ovarian cancer after adjusting for tumor characteristics, treatment, and sociodemographic factors. Although adjuvant chemotherapy was effective in prolonging survival, substantial numbers of women with ovarian cancer still did not receive chemotherapy.

Abstract
OBJECTIVE Recent reports have suggested that only half of women age > or =65 with advanced ovarian cancer are treated with platinum-based chemotherapy. The objective of this study was to compare the response to platinum-taxane chemotherapy and subsequent outcomes between patients older and younger than 65 years of age with stages IIIC-IV epithelial ovarian cancer (EOC). PATIENTS AND METHODS A cohort study was performed of all patients with stages IIIC-IV EOC who had their primary surgery at our institution from 1998 to 2004 and subsequently began platinum-taxane chemotherapy. Main outcomes were response to primary chemotherapy, platinum resistance and progression-free (PFS) and overall survival (OS). RESULTS A total of 292 patients began primary platinum-taxane therapy after surgery and comprised our study group. Of these, 108 (37%) were > or =65 years old and 184 (63%) were <65. Stage of disease, optimal cytoreduction rate, number of chemotherapy cycles and chemotherapy regimen alterations were similar between groups. Patients > or =65 achieved a clinical complete response with a similar frequency to those <65 (70% vs. 79%) and had similar rates of platinum sensitivity at 6 months (61% vs. 65%). Patients > or =65 had equivalent PFS (P=0.99) and OS (P=0.36) to those <65. Age > or =65 years was not independently associated with impaired survival. CONCLUSIONS Patients > or =65 years of age demonstrated similar rates of initial response, platinum resistance, PFS and OS to younger patients. Elderly women who can tolerate primary cytoreductive surgery should receive combination platinum-taxane chemotherapy.

Abstract
OBJECTIVES To evaluate the efficacy and toxicity of combination chemotherapy with intravenous irinotecan and oral etoposide in women with platinum- and taxane-resistant epithelial ovarian cancer. METHODS Between October 2002 and September 2005, we studied 27 women with platinum- and taxane-resistant epithelial ovarian cancer. Irinotecan was administered in an intravenous dose of 70 mg/m(2) as a 90-min infusion on days 1 and 15 of a 28-day cycle, and etoposide was administered in an oral dose of 50 mg/day on days 1 to 21. For heavily pretreated patients, the initial dose of irinotecan was lowered to 60 mg/m(2). Treatment cycles were repeated until disease progression or unacceptable toxicity. RESULTS All 27 patients were eligible and assessable. There were 11 partial responses and 1 complete response for an overall response rate of 44.4%. The median durations of overall response and of stable disease were 11 months and 8 months, respectively. The major toxicity was neutropenia (grade 3, 22.2%; grade 4, 37.1%). Diarrhea was infrequent and mild, and gastrointestinal toxicity was moderate and manageable. Acute myeloid leukemia (M5) developed as a secondary malignancy in 1 patient. CONCLUSIONS The results of our pilot study suggest that a combination of irinotecan and oral etoposide is effective and tolerable in women with platinum- and taxane-resistant epithelial ovarian cancer.

Abstract
Gynecological oncologists are faced with an increasing proportion of geriatric ovarian cancer patients. Comorbidities are frequently a matter of concern in this age group, and what is adequate treatment for such patients is still debated. The aims of this study were to analyze the feasibility of standard surgery and chemotherapy in a series of elderly ovarian cancer patients (>/=70 years) and to investigate the influence of age (70-75 vs >75 years) on survival. We retrospectively evaluated 89 elderly patients treated at our department between 1985 and 2005. Comorbidities, type of surgical procedure, complications, drugs and schedules of chemotherapy, number of cycles, toxicity, and clinical outcome were registered. Comorbidities were present in 71.9%. Only six patients were inoperable. Among the 83 patients who underwent surgery, 76.4% received adequate surgical treatment. Severe postoperative complications occurred in 16.8%, operative mortality was zero. A total of 801 cycles of chemotherapy were administered to 77 patients (median 10; range 1-38). Overall, G3-G4 toxicity was documented in 61.0%. The rates of dose reduction, treatment delay, and discontinuation were 13.0%, 20.7%, and 3.9%, respectively. Patients who received adequate surgery and those with residual disease <1 cm did significantly better than their counterparts (P= 0.04 and P < 0.001, respectively). No difference in survival according to age (70-75 vs >75 years) was found. Standard surgery and chemotherapy were feasible in elderly ovarian cancer patients. The type of surgery and the amount of residual disease, but not the age of the patients, significantly influenced the clinical outcome.

Abstract
BACKGROUND The purpose of the study was to evaluate first-line platinum/paclitaxel (Taxol) under phase III trial conditions in ovarian cancer (OC) patients aged >or=70 years. PATIENTS AND METHODS Phase III results of 779 patients with OC International Federation of Gynecology and Obstetrics (FIGO) stage IIB/IV treated with cisplatin/paclitaxel versus carboplatin/paclitaxel were retrospectively analyzed according to feasibility, toxicity (National Cancer Institute Common Toxicity Criteria) and quality of life (QoL) [European Organization for Research and Treatment of Cancer QoL questionnaire (EORTC QLQ-C30)] in patients aged <70 or >or=70 years. RESULTS One hundred and three (13%) patients were aged >or=70 years. Patient characteristics (<70 versus >or=70 years) showed significant differences with regard to Eastern Cooperative Oncology Group performance status, residual disease and constitutional factors but not to FIGO stage, histology or grading. Elderly patients received 98%, 100% and 96% of the recommended paclitaxel, carboplatin and cisplatin dose, respectively, per cycle. Early discontinuation was more frequent in elderly, although QoL, nonhematological and hematological toxicity were comparable between elderly and younger patients, except for febrile neutropenia (5% versus <1%, P = 0.005). There were no significant differences with regard to cycle delays, dose reductions or the use of granulocyte colony-stimulating factor and antibiotics. CONCLUSION Platinum/paclitaxel appeared to be feasible and tolerable in elderly patients under clinical trial conditions, but there seems to be a different investigators' estimation of toxicity and less intention to maintain trial treatment in elderly.

Abstract
BACKGROUND Numerous measures of comorbidity have been developed for health services research with administrative claims. OBJECTIVE We sought to compare the performance of 4 claims-based comorbidity measures. RESEARCH DESIGN AND SUBJECTS We undertook a retrospective cohort study of 5777 Medicare beneficiaries ages 66 and older with stage III colon cancer reported to the Surveillance, Epidemiology, and End Results Program between January 1, 1992 and December 31, 1996. MEASURES Comorbidity measures included Elixhauser's set of 30 condition indicators, Klabunde's outpatient and inpatient indices weighted for colorectal cancer patients, Diagnostic Cost Groups, and the Adjusted Clinical Group (ACG) System. Outcomes included receipt of adjuvant chemotherapy and 2 year noncancer mortality. RESULTS For all measures, greater comorbidity significantly predicted lower receipt of chemotherapy and higher noncancer death. Nested logistic regression modeling suggests that using more claims sources to measure comorbidity generally improves the prediction of chemotherapy receipt and noncancer death, but depends on the measure type and outcome studied. All 4 comorbidity measures significantly improved the fit of baseline regression models for both chemotherapy receipt (baseline c-statistic 0.776; ranging from 0.779 after adding ACGs and Klabunde to 0.789 after Elixhauser) and noncancer death (baseline c-statistic 0.687; ranging from 0.717 after adding ACGs to 0.744 after Elixhauser). CONCLUSIONS Although some comorbidity measures demonstrate minor advantages over others, each is fairly robust in predicting both chemotherapy receipt and noncancer death. Investigators should choose among these measures based on their availability, comfort with the methodology, and outcomes of interest.

Abstract
PURPOSE Efficacy of formulas calculating creatinine clearance (CrCl) to determine renal function eligibility (CrCl > 60 mL/min) for cisplatin-based chemotherapy has not been examined adequately in the bladder cancer population. We hypothesize these formulas may underestimate measured CrCl, and therefore the eligibility for cisplatin-based chemotherapy. PATIENTS AND METHODS A database of 208 patients with unresectable or metastatic bladder cancer treated on protocol at Memorial Sloan-Kettering Cancer Center (New York, NY) with cisplatin-based chemotherapy between 1983 and 1994 was examined retrospectively. The association between measured and calculated CrCl and the ability to complete three cycles (minimum therapeutic) of chemotherapy was examined. RESULTS Baseline measured CrCl was less than 60 mL/min in 16% compared with 12% to 44% using various formulas. Concordance between calculated and measured CrCl less than 60 mL/min was poor (range of kappa, 0.14 to 0.38). In patients older than age 65, 22% had a measured CrCl less than 60 mL/min, compared with 10% to 63% calculated using various formulas. Overall, 80% completed at least three cycles of cisplatin-based chemotherapy. The ability to complete at least three cycles was statistically significantly related with a measured CrCl more than 60 mL/min (P = .02), but not with calculated CrCl more than 60 mL/min. CONCLUSION Current formulas estimating CrCl tend to underestimate measured CrCl, especially in those older than 65 years. Depending on the formula used, up to 44% who actually received cisplatin-based chemotherapy based on measured CrCl would be deemed ineligible at present, potentially affecting survival outcomes. Methodology for determining CrCl and/or renal eligibility for cisplatin-based chemotherapy in patients with bladder cancer should be re-examined.

Abstract
PURPOSE For older breast cancer patients, there is limited evidence of the efficacy of adjuvant chemotherapy from randomized clinical trials. Our goal was to assess the relationship between adjuvant chemotherapy use and survival in a large, population-based cohort of older women with hormone receptor (HR) -negative breast cancer. METHODS We identified women age 66 and older diagnosed with HR-negative, nonmetastatic breast cancer from 1992 to 1999 in the Surveillance, Epidemiology and End Results (SEER) cancer registries. Chemotherapy use was identified in Medicare claims linked to SEER records. Clinical and sociodemographic predictors of chemotherapy use were identified using logistic regression. The effect of chemotherapy on survival was evaluated using propensity score methods and multivariable proportional hazards regression. RESULTS A total of 1,711 (34%) of 5,081 women with HR-negative breast cancer received chemotherapy within 6 months of cancer diagnosis. Chemotherapy use decreased with increasing age and comorbidity, and increased with year of diagnosis, tumor size, number of positive lymph nodes, and higher tumor grade. Adjuvant chemotherapy was associated with a mortality reduction of approximately 15% whether analyzed using propensity scores or standard multivariable methods. The greatest overall survival benefit was observed in patients with node-positive disease and in the node-negative patients most likely to receive chemotherapy. CONCLUSION This analysis suggests a survival benefit from adjuvant chemotherapy in older women with HR-negative breast cancer. The benefit of chemotherapy is most pronounced in the patients most likely to be selected for treatment, including those with involved lymph nodes or other high-risk disease characteristics.

Abstract
BACKGROUND In the past 25 years, clinical trials have demonstrated the benefits of chemotherapy for patients with aggressive non-Hodgkin lymphoma. The authors analyzed the predictors and outcomes of chemotherapy among elderly patients with lymphoma. METHODS Patients age >/=65 years who were diagnosed with Stage III and IV diffuse large B-cell lymphoma [according to the SEER Summary Staging Manual, 2000] between 1991 and 1999 in the Surveillance, Epidemiology, and End Results-Medicare data base were categorized by treatment: no chemotherapy, a doxorubicin-containing regimen, a regimen without doxorubicin, or chemotherapy not otherwise specified. Among the patients who survived for >6 weeks after diagnosis and who had a chemotherapy regimen specified, logistic regression analysis was used to identify predictors of doxorubicin-based treatment, and Cox proportional-hazards regression was used to analyze outcomes. RESULTS Less than 66% of patients received any chemotherapy in the 6 months after diagnosis, and 42% of untreated patients died within 6 weeks. Older age, congestive heart failure, and other comorbidities were strong predictors of treatment without doxorubicin. From 1991 to 1999, the proportion of patients who received doxorubicin increased from <20% to >50%. Patients who received doxorubicin survived more than twice as long (24.4 months) as patients who did not receive doxorubicin (11.2 months). Survival was no better among patients who received chemotherapy without doxorubicin than among patients who received no chemotherapy. CONCLUSIONS By 1999, doxorubicin-based chemotherapy had gained general acceptance for use among the elderly, although nearly 50% of elderly patients still were not receiving it. Given the clinical trial-based evidence of its benefits, in the absence of specific contraindications, most patients, including the elderly, should be treated with regimens that include doxorubicin.

Abstract
PURPOSE A prior analysis by the Southwest Oncology Group (SWOG) showed that women and African American patients were adequately represented on cancer clinical treatment trials but that older patients were substantially underrepresented. Twenty-five percent of patients > or = 65 years old were enrolled onto SWOG trials from 1993 to 1996, whereas 63% of all patients with cancer were > or = 65 years old. Recognition of this under-representation led to a change in Medicare policy in 2000 to include coverage of routine patient care costs of clinical trials. We conducted an updated analysis of accrual trends. METHODS The proportions of enrollment onto SWOG treatment trials by sex, race/ethnicity, and age (> or = 65 years) were computed for the years 1997 to 2000; corresponding rates in the United States were derived from US Census and National Cancer Institute Surveillance, Epidemiology, and End results data. Additionally, method of payment data were analyzed over time (1993 to 2003) to assess whether patterns in method of payment changed with the new Year 2000 Medicare policy on clinical trials coverage. RESULTS The results showed continued adequate representation by sex and race/ethnicity. Older patient accrual on SWOG trials increased significantly since 2000, with 31% of patients > or = 65 years old enrolled from 1997 to 2000 and 38% enrolled from 2001 to 2003 (v 25% from 1993 to 1996). The percentage of patients using Medicare plus supplemental insurance also increased beginning in 2000, whereas the percentage of patients using Medicare alone remained the same. CONCLUSION Method of payment analyses provided evidence that the Year 2000 Medicare policy change had a positive impact, but only for those patients with supplemental private coverage of coinsurance costs. Improvements in the Medicare payment structure could further increase older patient participation in clinical trials.

Abstract
BACKGROUND The American Cancer Society (ACS), the Centers for Disease Control and Prevention (CDC), the National Cancer Institute (NCI), and the North American Association of Central Cancer Registries (NAACCR) collaborate annually to provide information on cancer rates and trends in the United States. This year's report updates statistics on the 15 most common cancers in the five major racial/ethnic populations in the United States for 1992-2002 and features population-based trends in cancer treatment. METHODS The NCI, the CDC, and the NAACCR provided information on cancer cases, and the CDC provided information on cancer deaths. Reported incidence and death rates were age-adjusted to the 2000 U.S. standard population, annual percent change in rates for fixed intervals was estimated by linear regression, and annual percent change in trends was estimated with joinpoint regression analysis. Population-based treatment data were derived from the Surveillance, Epidemiology, and End Results (SEER) Program registries, SEER-Medicare linked databases, and NCI Patterns of Care/Quality of Care studies. RESULTS Among men, the incidence rates for all cancer sites combined were stable from 1995 through 2002. Among women, the incidence rates increased by 0.3% annually from 1987 through 2002. Death rates in men and women combined decreased by 1.1% annually from 1993 through 2002 for all cancer sites combined and also for many of the 15 most common cancers. Among women, lung cancer death rates increased from 1995 through 2002, but lung cancer incidence rates stabilized from 1998 through 2002. Although results of cancer treatment studies suggest that much of contemporary cancer treatment for selected cancers is consistent with evidence-based guidelines, they also point to geographic, racial, economic, and age-related disparities in cancer treatment. CONCLUSIONS Cancer death rates for all cancer sites combined and for many common cancers have declined at the same time as the dissemination of guideline-based treatment into the community has increased, although this progress is not shared equally across all racial and ethnic populations. Data from population-based cancer registries, supplemented by linkage with administrative databases, are an important resource for monitoring the quality of cancer treatment. Use of this cancer surveillance system, along with new developments in medical informatics and electronic medical records, may facilitate monitoring of the translation of basic science and clinical advances to cancer prevention, detection, and uniformly high quality of care in all areas and populations of the United States.

Abstract
OBJECTIVE Elderly patients are less likely to receive surgery and platinum-based combination chemotherapy than younger patients. We evaluated multi-institutional management of ovarian cancer in the elderly. METHODS Charts of women with ovarian, primary peritoneal or fallopian tube cancer from 1/1996-6/2004, age > or =70 years were reviewed. Age, stage, medical co-morbidities, surgery, chemotherapy, treatment modification, toxicity and survival were analyzed. Chi-square, logistic regression and survival analysis were used. RESULTS Of 131 patients, 90 were ages 70-79 (group 1 = G1) and 41 were >80 years of age (group 2 = G2). Surgery was performed in 80 patients in G1; 25 patients in G2 (P = 0.001). Among patients who underwent surgery, optimal debulking and post-operative complications did not differ between groups. Ninety-five percent of patients received platinum-based therapy and 83% received combination platinum/paclitaxel in G1, compared to 90% and 41%, respectively, in G2 (P < 0.001). Of those receiving platinum therapy, 36% in G1 and 41% in G2 required dose reductions or termination of therapy. Forty percent of G1 and 50% of G2 required a delay of therapy; the majority occurring in patients receiving combination therapy. Hematological toxicity increased with use of combination therapy, but not with advancing age or Charlson score. Successful debulking surgery significantly impacted survival, and when controlling for this factor, age was not a significant variable. CONCLUSION The extreme elderly had a decreased likelihood of receiving surgery and combination chemotherapy despite equivalent co-morbidities. In this analysis, optimal surgical cytoreduction had the greatest impact on survival.

Abstract
To determine the accuracy with which Medicare claims data measure chemotherapy use in elderly Medicare beneficiaries with cancer, we performed a criterion validation study. We compared gold-standard clinical trial data for 175 elderly cancer patients treated in two Cancer and Leukemia Group B (CALGB) breast and lung cancer trials (i.e., 45 from trial 9344 and 130 from trial 9730) with contemporaneous ambulatory and in-patient Medicare health insurance claims data from Centers for Medicare and Medicaid Services (CMS). The breast trial participants studied were those elderly enrolled between 1995 and 1997 and treated with doxorubicin and cyclophosphamide or this combination with paclitaxel. The lung trial participants studied were those elderly enrolled between 1998 and 2000 and treated with paclitaxel and carboplatin or paclitaxel alone. Comparing CALGB data with Medicare claims, we found the crude sensitivity for chemotherapy administration was 93% (95% confidence interval [CI] = 88% to 96%). Individual chemotherapy agents had similarly high sensitivities, ranging from 81% (95% CI = 70% to 89%) for carboplatin to 91% (95% CI = 79% to 98%) for cyclophosphamide. Agent-specific specificities were 100%. CMS data reliably captured repeat administration of chemotherapy to within one cycle. Administrative Medicare claims data appear to be a valid source of information for chemotherapy administered to elderly Medicare beneficiaries with cancer.

Abstract
Checkpoint kinase 2 (Chk2) is one of the critical kinases governing the cell cycle checkpoint, DNA damage repair, and cell apoptosis in response to DNA damaging signals. In the present report, we demonstrate that Chk2 kinase is degraded at the protein level in response to cisplatin through ubiquitin-proteasome pathway. This degradation was independent of the Thr68 phosphorylation, ATM kinase, and BRCA1 tumor suppressor. Examination of Chk2 protein revealed a decreased expression of Chk2 protein in cisplatin-resistant ovarian cancer cell lines, suggesting that degradation or decreased expression of Chk2 is partially responsible for chemo-resistance. Site-directed mutation of the putative destruction box in the Chk2 protein did not affect the Chk2 degradation induced by cisplatin. Therefore, these results are the first to indicate a novel mechanism of regulating Chk2 in cisplatin-induced resistance of cancer cells.

Abstract
The aging population is the fastest growing segment of our population. Over the last century, the average life expectancy has increased by 25 years. The incidence of ovarian carcinoma, seen primarily in postmenopausal women, is, therefore, expected to increase. The current standard treatment of ovarian cancer has been determined on the basis of prospective, randomised clinical trials carried out by cooperative groups. Sixty-one percent of new cancer cases occur in women >65 years of age. Despite this fact, enrollment in clinical trials has been exceedingly low. In turn, this causes suboptimal treatment for a very fatal disease. The aetiology of this is multifactorial, and strategies for improvement are lacking. Elderly patients may be barred from participation based on physician biases alone. Elderly patients may have limited access to academic centres where clinical trials are conducted or be excluded on the basis of unrealistic inclusion criteria. As physicians, it is our duty to understand the elderly patient and the comorbidities in this age group that may influence the tolerability and toxicity of conventional therapies. Therefore, it is imperative that we make a conscious effort to examine ways in which we may improve enrollment of elderly women with ovarian cancer in clinical trials.
